Structural Evolution of Antigorite by High‐Velocity Impacts

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Serpentine is a major hydrous mineral present in hydrous asteroids that have evolved through planetary impacts. Understanding its dynamic behavior is essential to elucidate the redistribution and retention of water during high‐velocity impact processes. The shock response of antigorite was examined at pressures up to 106 GPa using laser‐driven

An Overview of Solar Orbiter Observations of Interplanetary Shocks in Solar Cycle 25

The Astrophysical Journal Supplement Series
Interplanetary (IP) shocks are fundamental constituents of the heliosphere, where they form as a result of solar activity. We use previously unavailable measurements of IP shocks in the inner heliosphere provided by Solar Orbiter, and present a survey of

Solar and interplanetary particles re-accelerated at the solar wind termination shock [PDF]

Advances in Space Research, 1999
We consider the acceleration of solar/interplanetary particles at the solar wind termination shock, predict the expected composition and energy spectra, and discuss possible observable ...

Experimental Constraints on the Formation of Niningerite and Oldhamite Under Highly Reducing Conditions: Implications for Sulfide Formation in EH3 Chondrites

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Enstatite chondrites record highly reducing conditions in the early solar nebula, yet the origin of their abundant sulfides remains unclear. Niningerite (MgS) and oldhamite (CaS) are ubiquitous in EH3 enstatite chondrites and distinguish them from other chondrite groups.

Alfvénic Poynting Flux Characterized by a Substorm‐SMC Cycle and Ionospheric Influence

Space Weather, Volume 24, Issue 8, August 2026.
Abstract Geomagnetic substorms are fundamental processes of explosive geospace energy release within the Earth's magnetotail, which are usually divided into three phases: the growth phase, the expansion phase, and the recovery phase. Large‐scale electromagnetic energy transport during a geomagnetic substorm is in the form of Alfvén waves, transmitting ...

Electron Acceleration in Time-dependent Kinematic Three-dimensional Magnetic Reconnection: The Role of Induced Electric Fields and Magnetic Topology

The Astrophysical Journal Supplement Series
Particle acceleration during magnetic reconnection is a key process in space physics and astrophysics, yet the direct role of induced electric fields in fully time-dependent three-dimensional (3D) topologies remains poorly quantified.

Ground‐Based Solar Radio Observations From the Mexican e‐Callisto Stations During the May 2024 Extreme Space Weather Events

Space Weather, Volume 24, Issue 8, August 2026.
Abstract The period from 1 to 14 May 2024 was marked by some of the most intense solar activity of Solar Cycle 25, including multiple X‐class flares, fast coronal mass ejections (CMEs), and diverse solar radio emissions. We present observations from the Mexican e‐Callisto network (REC‐Mx), including long‐duration continuum emissions (CTMs), Type II ...

Breeding 5.0: Artificial intelligence (AI)‐decoded germplasm for accelerated crop innovation

Journal of Integrative Plant Biology, Volume 68, Issue 8, Page 2340-2352, August 2026.
This review synthesizes applications of AI and robotics for germplasm characterization and breeding, proposing the Breeding 5.0 framework with its “Breeding Flywheel”. By decoding germplasm's multidimensional architecture, AI drives data‐empowered automation cycles to accelerate germplasm innovation, redefining solutions for global food security ...

Energetic particle investigation using the ERNE instrument

Annales Geophysicae
During solar flares and coronal mass ejections, nuclei and electrons accelerated to high energies are injected into interplanetary space. These accelerated particles can be detected at the SOHO satellite by the ERNE instrument.

The Effect of Large-scale Magnetic Fluctuations on Energetic Particle Profiles across Interplanetary Shocks

The Astrophysical Journal
In situ observations of energetic particles associated with interplanetary (IP) shocks, known as energetic storm particle (ESP) events, often show time-intensity profiles quite different from predictions of classical diffusive shock acceleration theory ...
